Embodiment 1
[0045] The production process of the medical Ti-6Al-4V alloy wire with a diameter of 2.0mm for manufacturing children's intramedullary nails, its implementation steps are as follows:
[0046] (1) Melting
[0047] The raw material is grade 1 sponge titanium, and the sponge titanium, aluminum vanadium alloy, aluminum beans, iron powder, and titanium dioxide are mixed according to a certain proportion, and then pressed with a press to form an electrode. Put it into a vacuum consumable arc melting furnace and melt it 3 times to make alloy ingot.
[0048] (2) forging
[0049] The ingot is heated to 1050℃~1150℃ by an electric furnace, and the blank is forged Final forging temperature ≥ 830°C.
[0050] (3) Double rolling with large deformation
[0051] Use an electric furnace to heat to 900°C-950°C (±5°C), hold time for 60-90min, and finish rolling temperature ≥ 800°C.
[0052] (4) cold drawn
[0053] Will After the blanks are subjected to temperature-controlled hot-draw...
